Answer

Distributive property: a(b + c) = ab + ac

Work Step by Step

The distributive property states that when we multiply a number by a sum of two numbers, we would get the same result as if we multiplied the number by each of the terms and then added the results. The expression 2(A + B) = 2A + 2B shows exactly this: multiplying 2 by the sum of A and B would yield the same result as multiplying 2 by A and B and then adding the results.
